IMPROVEMENT IN INSULATORS FOR MUSICAL INSTRUMENTS.

Specification forming part of Letters Patent X0. 155,099, datedSeptember 15, 18' 4 application filed August 10, 1874.

To all whom it may concern:

Be it known that I, WVILLIAM R. MILLER, of Baltimore city, in the Stateof Maryland, have invented a new and Improved Piano- Sound-InsulatingAttachment; and I do here by declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawing forming a part of this specification. in which-Figure 1 is an elevation partly broken away; Fig. 2, a plan view.

The invention relates to and consists in novel means for destroying theconductivity of sound in legs of pianos and other similar musicalinstruments, as hereinafter described, and subsequently pointed out inthe claim.

Arepresents the top of the piano-leg, made of any preferred form, andhaving an upper concavity of any desired shape. In this concavity Iplace a correspondingly-shaped block of glass or other insulatingmaterial, B, raised above the surface of said top A, detachably held byscrews 0, and provided in the center 1 with a hole, I), decreasingupwardly or from bottom toward the top. In the latter fits the head d ofscrew D, said head being tapered and of such a magnitude as will allowit to be drawn up some distance in the hole b. The screw is thus broughtinto contact only with the glass, that will be an effectual barrier tothe transmission of sound, and allow the volume emitted by theinstrument to be thus preserved in its integrity without dispersion,loss, or impairment.

Having thus described my invention, what I claim as new is Thehereinbeiore-described combination of insulatingblock B and screw D,having, respectively, the tapering hole and head I) (I, to connect amusical instrument with its legs, and prevent the transmission of soundfrom the instrument through the legs to the floor.
